What must occur for protein translation to begin? A water molecule must be added to the protein chain. A peptide bond must form between subunits of mRNA. The amino acid Cys must be picked up by tRNA. The codon AUG must be identified.

For protein translation to begin, the codon AUG must be identified.

PROTEIN SYNTHESIS:

However, for translation to begin, a specific mRNA codon called START CODON with the sequence: AUG must be identified first.

A peptide bond must form between subunits of mRNA

Explanation:

Translation occur in the RIBOSOMES and it is the process where protein is produced by reading the genetic code of messenger RNA.

For translation to occur,A peptide bond must form between subunits of mRNA because it is through the formation of peptide bond between subunits of mRNA that the small ribosomal subunit binds to the start of the mRNA sequence. Then a transfer RNA molecule that carry Amino acids methionine binds to the start codon of the mRNA .The start codon in all mRNA molecules has the sequence AUG and codes for methionine.

answer; /// i believe that the correct answer is (50%);

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck
